## `llvm-objcopy --strip-dwo` strips out dwo sections, as a result, the index of
## the symbol table, the indices of the symbols and the indices of the sections
## which go after the removed ones will change. Consequently, the fields Link,
## Info and the content of .group need to be updated.

## Note. 'Signature' is generated using 'Link' and 'Info', so checking it
## validates updating these fields.
